Rivista di astronomia e scienze affini, 1911, a. 5, n. 06 (June)
An 1911 Italian astronomy journal issue from the Società astronomica italiana, produced for a scholarly readership and held by the Turin Astrophysical Observatory. Its pictures are plain technical diagrams: a celestial sphere grid with numbered star positions plotted against compass points, a flat projection of the same grid, and a perspective geometry figure with labeled lines and planes. A designer might take the spare line-drawn grids and lettered construction diagrams as a model for minimal scientific infographics.
